RPM Air-Gap Small Block Ford 351W Intake Manifold - Chrome Plasma Finish

The Edelbrock RPM Air-Gap 351W #7581-CP intake manifold is designed for street and high performance 351-427 c.i.d. 351W Ford V8's, the RPM Air-Gap incorporates the same race-winning design that's been used on our Victor Series competition intakes for decades. The Air-Gap design features an open air space that separates the runners from the hot engine oil resulting in a cooler, denser charge for more power. Larger cross sectional area and a taller carb flange than #7181 for compatibility with large displacement, stroker 351W based engines. Includes bosses for nitrous and rear water crossover. Edelbrock carbs will work with Ford automatic overdrive trans (AOD) when used with Lokar bracket SRK-4000, for more info call (865) 966-2269 or go to www.lokar.com. The Edelbrock RPM Air-Gap 351W #7581 intake manifold is a dual-plane, high-rise intake with a 180-degree firing order to produce incredible top-end horsepower while retaining good throttle response. The larger plenum and runners match the free-flowing exhaust, high-lift cams and other modifications of a high output engine. The Edelbrock RPM Air-Gap 351W #7581-BP also features a natural aluminum finish for a classic look. For the ultimate "Made in USA" quality, every Edelbrock intake manifold is cast and machined in the USA.
